Mexican officials have detained 94 illegal immigrants, including 19 from the Indian subcontinent, packed into a truck bound for the U.S. border, authorities said on Tuesday.

Among the people found near the southern city of Tuxtla Gutierrez, capital of Chiapas state, were 10 Nepalese and nine Bangladeshis trying to reach the United States, officials said.

Apprehensions of Asians immigrating illegally to the United States have increased sharply in recent years, according to the U.S. Department of Homeland Security.

Authorities said the migrants were traveling in inhumane conditions. The driver of the vehicle, who was from central Mexico, was arrested on human trafficking charges.

The truck set out from Huehuetenango, Guatemala, and police detected the migrants with an X-ray at a checkpoint outside Tuxtla Gutierrez after midnight on Monday. The migrants were on their way to the United States, state prosecutors said.

The non-Asian migrants were from the Central American nations of Guatemala, El Salvador and Honduras.

The entire group, which included seven minors, is likely to face deportation proceedings.

Between 2007 and 2011, the most recent year for which statistics were available, the number of Indian nationals apprehended by U.S. authorities jumped from less than 1,000 annually to nearly 4,000. The numbers of Bangladeshi, Nepalese and Sri Lankan migrants detained have also increased.

The Central Americans were charged between $4,000 and $5,000 for the journey, while the Asian migrants had to pay between $6,000 and $8,000, according to the National Migration Institute.

An Indian national was among a group of 165 migrants rescued by Mexican troops in June, after being kidnapped near the U.S. border and held in the state of Tamaulipas.
